摘　　要：粉煤灰复垦区杨、柳、榆、刺槐的生物量刘雅荣，刘建伟，王世绩，冷国友，周树理，程锦山关键词煤矿复垦区，杨，柳，榆，刺槐，生物量淮北地区煤矿开采后，形成大面积的塌陷区，造成可利用的土地面积减少，生态环境恶化。据统计，类似淮北的情况，全国以每年２万ｈｍ２的...Coal ash from thermal power factory was filled in the collapsed area formed by coal-digging,and then 30 cm of soil is covered onto the coal ash.The result was that four tree species grew normally under proper fertilization and irrigation condition. Their biomass are:4-year-old poplar 51.95 kg,5-year-old Robinia 76.56kg,5-year-old Salix 44.15 kg,5-year-old Ulmus 38.98 kg. Biomass distribution of the inside tree was:trunk 46.3%～63.0%,branches 17.4%～23.4%, roots 14.3%～25.9%and leaves 2.5%～4.6%. The conclusion was that the planting of alkaline resistant tree species or shrubs on the reclaimed coal ash is an effective way in the improvement of ecological environment and soil utilization.
